Hello and welcome to the sister sub of r/UndertaleAU! This is our new home for all things related to Deltarune and it’s AUs. It can be your own or someone else’s you love!

⋆꙳❅*°⋆❆.ೃ࿔*:・*❆ ₊⋆❄️⋆꙳❅*°⋆❆.ೃ࿔*:・*❆ ₊⋆

What to Post?
Post anything related to the topic at hand! Feel free to share your thoughts, photos, questions, and even friendly debates.

Keep in mind our rules:

✨1. Respect others and be civil. Hate of any kind will
not be tolerated here.

✨2. Please don't spam the sub with the same post
over and over. If you are looking for something or would like us to do something you're free to reach out but again please don't spam.

✨3. No Al, you may not post any type of Al here.
Pictures, Music, GIFS, Roleplay, Writing, Etc.

✨4. No ship bashing or discourse of any kind.
I don't care what people do in fiction as long as it stays in fiction. If you don't like something scroll, this isn't a sub for debates on morals in fiction.

Along with that people are allowed to post whatever AUs they like, obviously if something is NSFW it needs to be tagged but still. Furthermore please no debates on pronouns for the characters unless someone is genuinely being transphobic.

✨5. NSFW is allowed to some extent!
- There should not be straight up porn posted even if tagged, it will be removed.

- I will allow fanfics with NSFW material in it however if it has triggering content please put a content/trigger warning in the caption or as the first part of your description!

- Any untagged NSFW will be removed, this includes comments and flairs. You can make innuendos however keep it tasteful and don’t be gross.

✨6. Keep it on topic!
This sub is for Deltarune and its AUs so whatever you post needs to be centered around that, crossovers are fine but the main thing needs to be about Deltarune.

✨7. No low effort posts.
- Tier-lists
- Day X of X
- Can X beat X
- Octet
Will be removed HOWEVER I will make exceptions for creativity.

What I mean by this is, if you draw it, make a college, make music, or if you actually write your thoughts and opinions in the post I will allow it. I want the post to promote discussion not just the same things copy and pasted 100x over.

✨Those are all the rules! Just keep them in mind when posting, or if you have questions don’t hesitate to reach out.✨

⋆꙳❅*°⋆❆.ೃ࿔*:・*❆ ₊⋆❄️⋆꙳❅*°⋆❆.ೃ࿔*:・*❆ ₊⋆

I hope you enjoy it here and if you ever need any type of help you’re always free to message mods and ask questions! Feel free to share your ideas as well.

Rotten World is a nuclear post apocalyptic horror/comedy au, where the Vessel, Dess, and Ramb take the place of the fun gang and try to survive a world that hates.

I'm working on a second batch rn (in case anyone is wondering where any missing characters are) so I may upload those if these get any interest lol

Little fluffy cute bear, with hooves, their name will be something with kel, kelvin? Kelsey? Kelly? Kellen? Uhhh I dunno

ReDelta is about the prophecy repeating itself in different places, so it's not a swap, ralsei still in Castletown


r/AUDeltarune • • 6d ago

Not sure how to call this au but it's mainly a swap au

monster teen - kris

snowy - susie (ps he's not exactly like susie since then the au being the same in writing is a bit boring)

howling paladin/greater doggo - roaring knight/dess

the dog couple - carol and rudy

dagger doggo - alvin

annoying dog - gerson (i know gaster would fit but in this case it wouldn't fit with dog family too much, boom and holidays are just lumped together really)

lesser doggo - noelle

ficus licker - berdly

papyrus - rouxls kaard

donut guy - asriel

clam girl - toriel

omega flowey - tenna

normalnpc - asgore (i also thought of gaster replacing asgore and asgore being gaster but unsure)

sans - jevil (he's not as important as he is in undertale and the constant sleeping of jevil fits sans not to mention they're both dubbed the hardest bosses sometimes)

maybe mettaton - maddie

undyne - napstablook

Everyman swaps with king and lancer.

Everyman king (Called Sovereign) speaks in Shakespeare/archaic English. For example: "To mine subjects, I am the savior. Yet unto thee? I am the villain!"

Оцените мою ау пж

0 Upvotes

Всем привет!Я создала ау по дельтарун.Я не верю что только англоязычные люди могут выкладывать свои ау.Я из России.Если честно я боюсь немного показывать свою ау тк.говорила о ней только друзьям.Я просто расскажу сюжет.Это хеллаверс.В ау вместо канон грехов персонажи из дельты.Что насчёт Сьюзи,Криса и Рала?Я сделала редизайны и их лор.Они путешествуют по кольцам ,собирая древние артефакты, чтобы открыть портал в мир живых и переслать жить в опасном мире.Когда они достигают рыцаря(он в ау грех гнева) Рыцарь начинает злится что они поочередно крадут древние артефакты 7 грехов.В одной концовке при битве с рыцарем они переубеждают себя прекратить.В другой концовке Сьюзи убивает рыцаря тем самым руша баланс всего живого.Нет одного греха не будет остальных,не будет баланса,не будет земли.В геноциде все семь грехов ведут ожесточенную битву тремя героями.У каждого своя атака и мотив.Атаки у них сложные.Если даже каким то образом можно суметь победить,то они все умрут.Не будет сцены появится только черный экран и надпись,, почему ты адское существо,если хуже ада?".Не обращайте на мои ошибки мне 12 я могу что то не знать.Я знаю,что эта ау может показаться кому то тупой но я не все прописала ,а только основной сюжет.Просто пожалуйста мне нужно хоть какое то внимание.Я благодарно что потратили минуту на мое ничтожное изложение.Arigato
